WHITE MOP WRINGER 1' MOP-WRING'ER.

srncrrron'rloiv forming part of Letters Patent No. 724,634, dated April 7, 1903.

Application filed July 22, 1902.

To all whom it may concern:

Be it known that We, OLIN N. WARDWELL, residing at Baldwinsville, in the county of Worcester and State of Massachusetts, and 5 HUBERT 0. WHITE, residing at Jamaica, in

the county of Windham and State of Vermont, citizens of the United States, have invented a new and useful Mop-Wringer, of which the following is a specification.

The invention relates to improvements in in op-wringers,

The object of the present invention is to improve the construction of mop-wringers, more especially the construction of the pressers or presser-boards, and to provide a simple and comparatively inexpensive construction designed for wringing mops having round headsand adapted to apply a uniform and yielding pressure to the solid round portion of thehead and an unyielding pressure to the lower or outer flexible portion of the mop-head.

A further object of the invention is to provide a presser or presser-board which will cause a round mop-head to automatically ad- 2 5 just itself to the mopwringer and which, should a round mop-head be inserted too far into it, will automatically press the same upward and apply a uniform pressure to the' Like numerals of reference designate cor responding parts in all the figures of the drawlugs.

1 and 2 designate stationary and movable Presser-boards mounted in a mop-wringer 3,

constructed similar to that shown and de- Serial No. 116,571. (No model.)

scribed in Patent No. 698,773, granted to Hubert 0. White on or aboutthe 29th day of April, 1902, with the exception of the press-v ers or presser-boards herein shown and described, and as the presser-boards are applicable to various mop-wringers, and especially .5 5

to that shown and described in the said patent, a description of the stationary and movable presser-frames and the means for operating the movable presser-framesis unnecessary.

The stationary presser-board 1 is provided with perforations 4L, and the movable presserboard 2 isimperforate. Each presser-board, which is provided with a flat or straight lower portion -5, has an intermediate upwardlyextending outwardly bowed transverselycurved portion 6, forming an inclined wall 7, adapted, should a round mop be introduced too far into the mop-wringer, to press or force the same upward, so that the solid inflexible 7o portion of the mop-head will be properly positioned with relation to the presser-board to receive a uniform pressure without interfering with the squeezing action of the presserboard on the outer or lower flexible portion of the mop head. The outwardly bowed transversely-curved portion may be downwardly-tapered and rounded at the base, as illustrated in Figs. 1 to 4, inclusive, or it may be made substantially of the same width, as shown in Fig. 5, in which the outwardlybowed portion has approximately parallel side edges 8, or a strictly semiconical outwardlybowed portion 9 may be used, as shown in- Fig. 6 of the drawings. The outwardly-bowed portion extends downward from the upper edge of the presser-board, and it terminates short of the bottom edge of the same to provide the lower straight portion 5, and it is also spaced from the side edges of the presserboard, which is provided with side flanges 10, designed to be provided with suitable perforations for the reception of fastening devices for securing the presser-board in position in the mop-wringer. The presser-board may be constructed of metal or any other suitable material.

It will be seen that the presser-board is exceedingly simple and inexpensive in construction,that as it is provided with abowed or transversely-curved surface and a flat or straight surface it is especially adapted for squeezing or wringing a round mop,and that as the transversely-curved surface or portion is arranged at an inclination and gradually merges at the bottom into the flat surface by an easy slope a substantially uniform pressure is brought to bear on all parts of a round mop. Furthermore, it will be clear by this construction that if a mop be inserted too far into a wringer the transversely-curved inclined portions will press the mop upward and cause the same to automatically adjust itself to the presserboards. Besides being adapted to exert a uniform pressure on round mops the pressure-board is adapted for wringing flat mops and will bringa uniform pressure to bear on all parts of a mop adjacent to the handle.

The transversely-bowed downwardly-inclined portion may be varied in size to adapt it for operating on mops of different sizes and makes, and the presser-boards may also be reinforced by exterior ribs similar to those shown in the said patent.

Either of the presserboards of a mopwringer may be provided with perforations or be imperforate, and, if desired, the improved presser-board may be used in connection with an ordinary straight presser-board or the like, and we desire it to be understood that changes in the form, proportion, size, and the minor details of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

What we claim is-- 1. In a mop-wringer, a presser-board having a straight or fiat lower face and provided with a downwardly inclined transverselycurved facelocated above the flat face and provided with a tapering bottom portion merging into the lower straight face, substantially as and for the purpose described.

2. In a mop-wringer, a presser-board provided with a downwardly inclined transversely-curved face having a tapering bottom portion, substantially as and for the purpose described.

In testimony that we claim the foregoing as ourown we have hereto afiixed our signatures in the presence of witnesses.
